guisher will be illustrated fully by the respective
manufacturers on request.

GLOSSARY

Below is a brief description of some technical
terms used in this manual.
SELF-CALIBRATION
This procedure calculates suitable correction coef-
ficients starting from known operating conditions.
It improves the machine accuracy by correcting
to a certain extent the calculation errors that may
result from the alteration of the machine's features
over the course of time.
AWC
Auto Width Calculation acronym
AWD
Auto Width Device acronym
CALIBRATION
See SELF-CALIBRATION
CENTRING
Procedure for positioning the wheel on the wheel
balancer shaft to ensure that the shaft axis cor-
responds to the wheel rotation axis.
BALANCING CYCLE
Sequence of operations to be performed by the
user and the machine from the beginning of the
spin until the wheel is braked to a stop after cal-
culating the unbalance values.
CONE
Conical element with a central hole which, when
inserted on the wheel balancer shaft, is used to cen-
tre the wheels having central holes with a diameter
ranging between maximum and minimum values.
DYNAMIC BALANCING
Procedure for unbalance compensation by apply-
ing two weights, one on each of the two wheel sides.
STATIC BALANCING
Procedure for correcting only the static element of
the unbalance, by applying only one weight, usually
at the centre of the rim well. Accuracy increases
as the width of the wheel decreases.
FLANGE (plate - wheel balancer)
Circular crown-shaped disk against which the
disk of the wheel mounted on the wheel balancer
rests. Also used for keeping the wheel perfectly
perpendicular to its rotation axis.
FLANGE (adapter - centring accessory)
76
Device for supporting and centring the wheel. Also
used for keeping the wheel perfectly perpendicular
to its rotation axis.
It is mounted on the wheel balancer shaft.
FSP
Fast Selection Program acronym
RING NUT
Wheel blocking device on the wheel balancer, fit-
ted with elements for coupling with the threaded
hub and side pins for tightening it.
LOCKING DEVICE
Wheel clamping device on the wheel balancer
only used for versions with the automatic wheel
clamping system.
ICON
Symbol displayed on the screen illustrating a
button, indicating the graphic representation of
a control.
SPIN
Procedure starting from the action that causes
the wheel to rotate and the subsequent rotation
of the wheel.
THREADED HUB
Threaded part of the shaft on which the ring nut
is engaged to lock the wheel. It is supplied disas-
sembled from the machine.
OPT
Optimisation abbreviation.
MEASURING DEVICE (measuring arm)
Mobile mechanical element that, when brought
into contact with the rim in a specific position,
measures the geometric data: distance, diameter.
Data can be measured automatically if the sensor is
equipped with suitable measurement transducers.
RPA
Acronym of Ricerca Posizione Automatica (Auto-
matic Position Search).
ULTRASONIC SENSOR
Electronic component that, together with the
information collected by the internal sensor,
makes it possible to measure the wheel width.
This measurement is taken by transmitting and
receiving ultrasonic wave trains.
UNBALANCE
Uneven distribution of the wheel mass that gener-
ates centrifugal forces during rotation.
SENSOR
See MEASURING DEVICE.
